LIMITED WARRANTY TERMS AND CONDITIONS
Product Limited Warranty
Subject to the following terms and conditions, Trimble Navigation
Limited ("Trimble") warrants that for a period of one (1) year from date
of purchase this Trimble product (the "Product") will substantially
conform to Trimble's publicly available specifications for the Product
and that the hardware and any storage media components of the
Product will be substantially free from defects in materials and
workmanship.
Product Software
Product software, whether built into hardware circuitry as firmware,
provided as a standalone computer software product, embedded in flash
memory, or stored on magnetic or other media, is licensed solely for use
with or as an integral part of the Product and is not sold. If accompanied
by a separate end user license agreement ("EULA"), use of any such
software will be subject to the terms of such end user license agreement
(including any differing limited warranty terms, exclusions, and
limitations), which shall control over the terms and conditions set forth
in this limited warranty.
Software Fixes
During the limited warranty period you will be entitled to receive such
Fixes to the Product software that Trimble releases and makes
commercially available and for which it does not charge separately,
subject to the procedures for delivery to purchasers of Trimble products
generally. If you have purchased the Product from an authorized Trimble
dealer rather than from Trimble directly, Trimble may, at its option,
forward the software Fix to the Trimble dealer for final distribution to
you. Minor Updates, Major Upgrades, new products, or substantially
new software releases, as identified by Trimble, are expressly excluded
from this update process and limited warranty. Receipt of software Fixes
or other enhancements shall not serve to extend the limited warranty
period.
For purposes of this warranty the following definitions shall apply: (1)
"Fix(es)" means an error correction or other update created to fix a
previous software version that does not substantially conform to its
Trimble specifications; (2) "Minor Update" occurs when enhancements
are made to current features in a software program; and (3) "Major
Upgrade" occurs when significant new features are added to software, or
when a new product containing new features replaces the further
development of a current product line. Trimble reserves the right to
determine, in its sole discretion, what constitutes a Fix, Minor Update,
or Major Upgrade.
Warranty Remedies
If the Trimble Product fails during the warranty period for reasons
covered by this limited warranty and you notify Trimble of such failure
during the warranty period, Trimble will repair OR replace the
nonconforming Product with new, equivalent to new, or reconditioned
parts or Product, OR refund the Product purchase price paid by you, at
Trimble's option, upon your return of the Product in accordance with
Trimble's product return procedures then in effect.

GreenSeeker RT200 System Installation and Operation Guide
Safety Information
Before you start the installation, you must read and understand the information
contained in this section.
Always follow the instructions that accompany a Warning or Caution. The information
they provide is intended to minimize the risk of personal injury and/or damage to
property. In particular, observe safety instructions that are presented in the following
format:
C
WARNING – This alert warns of a potential hazard, which, if not avoided, can cause
severe injury.
C
CAUTION – This alert warns of a hazard or unsafe practice which, if not avoided, can
cause injury or damage.
Note – An absence of specific alerts does not mean that there are no safety risks involved.
Warnings
C
WARNING – If someone else attempts to drive the vehicle while you are working on or
under it, you can suffer serious or fatal injuries. To avoid this possibility, install a lockout
box on the battery terminal to prevent the battery from being reconnected, remove the
key from the vehicle's ignition switch, and attach a "Do not operate" tag in the cab.
C
WARNING – Vehicle cabs can be quite high in the air. To avoid potentially serious injury
through falling from this height, always use the steps and handrails, and face the vehicle,
when you enter or exit it.
C
WARNING – Do not remove/cut or bypass the auto adapter end of the power adapter
cable for the PDA. Do not connect directly to 12 V DC as this will cause immediate failure
of the PDA.
C
WARNING – There are no field serviceable components of the electronic system; do not
attempt any field repair of a malfunctioning controller or sensors. If you experience
operating problems, contact your local dealer or representative or GreenSeeker
distributor for assistance.
C
WARNING – The system installation may bring you into contact with chemical substances,
such as oil, which can cause poisoning. Wash your hands thoroughly after you finish
working on the system.

C
WARNING – Battery posts, terminals, and related accessories contain lead and lead
compounds, which can cause serious illness. To avoid ingesting lead, wash your hands
thoroughly after touching the battery.
C
WARNING – Always wear protective equipment appropriate to the job conditions and
the nature of the vehicle. This includes wearing protective glasses when you use
pressurized air or water, and correct protective welder's clothing when welding. Avoid
wearing loose clothing or jewelry that can catch on machine parts or tools.
C
WARNING – Parts of the vehicle may be under pressure. To avoid injury from pressurized
parts, relieve all pressure in oil, air, and water systems before you disconnect any lines,
fittings, or related items. To avoid being sprayed by pressurized liquids, hold a rag over fill
caps, breathers, or hose connections when you remove them. Do not use your bare hands
to check for hydraulic leaks. Use a board or cardboard instead.
C
WARNING – Always read chemical manufacturer's instructions before handling or
spraying chemicals.

Introduction
System overview
The GreenSeeker RT200 variable rate application and mapping system is a tool for
variably applying agricultural chemicals based on real-time measurements of the crop.
The sensors measure NDVI (Normalized Difference Vegetation Index) of the plants
while traversing the field, and the software collects the data that can be used to
generate maps of the NDVI and rates (where applicable) for crop analysis and
historical data collection. This type of data can be used in conjunction with other
agronomic references to index nutrient response, crop condition, yield potential,
stress, pest, and disease impact in a quantitative manner. The RT200 system can be
used to monitor changing crop conditions during the growing season and the effects of
different levels of an input compared to a defined standard.
The applicator allows you to variably apply agricultural chemicals in real time (as the
applicator passes over the crop). The NDVI-based variable rate algorithm and
parameters may be selected in the field, and all rate changes are then made "on the go,"
so there are no lengthy delays between evaluating the crop and application. When
applying fertilizer or other material, the NDVI, the target rate on, and the applied rate
are mapped simultaneously with the GreenSeeker RT200 system. Some spray
controllers do not respond with an 'As Applied' value.
The GreenSeeker optical sensor emits light at two specific wavelengths, and measures
the reflected light. The microprocessor in the sensor analyzes the reflected light and
calculates the resulting Index value. The data from each sensor is collected by the
RT200 interface module, processed and then transmitted to a PDA in the cab running
one of the following:
•
RT Commander software
•
Version 3.0 or later of the AgGPS® FmX® integrated display
The RT Commander software displays the NDVI and location in real-time, logs the
output data to a file, and sends the appropriate rates to the applicator's rate controller
or FmX integrated display. The logged data is easily transferred to a desktop computer
for analysis.
The ruggedized PDA (Personal Digital Assistant) could be a Trimble Recon® or
Nomad® handheld computer. In this document, “PDA” refers to both handheld models:
If anything refers to only one model, this is clearly indicated.

Introduction
You must take good care of your GreenSeeker RT200 variable rate application and
mapping system to maintain high performance. At the end of each day of spraying, do
the following:
•
Check the detector and light source windows for dust and dirt, and wipe clean
with a soft rag.
•
Do not leave the GreenSeeker systemoutdoors during extreme weather
conditions. Wide temperature variations may reduce the operating life of the
system.
•
Do not store a GreenSeeker system with the sensors facing upward. Doing so
may allow water to collect around the windows and gaskets, causing seal
failures in those areas. Direct sunlight can in some cases also focus enough
energy into the sensor to damage the detector.
•
When rinsing off the machine, take care not to use high pressure to directly
spray the sensors. Even though all connectors and modules are fully sealed,
there still exists potential leakage from a pressurized stream.
•
Every time the spray tank is filled, take a soft cloth and wipe the lenses of the
sensors if needed. Try to check sensors at least once a day during full-time
operation.
•
Be more aware of cleaning the sensors directly behind the machine.
•
If you do not have ground protection devices on the boom, such as gauge wheels
or skids, take extra care to not run the boom into the ground. Also, be aware of
sensor vulnerability to stationary structures in the field. Sensors are usually
mounted on the front of the boom and do not have rigid protection.
•
Rinse the boom after the end of every day. This will keep the system clean and
wash any corrosive materials off. This will greatly extend the life of your
machine.
•
At the beginning of each season, and periodically as required, check the hose
clamps, plumbing connections, and other fluid handling system components for
tightness and leak free operation.
•
Make sure all wiring harness components remain fastened to the boom as to not
obstruct the view of the sensors and are free of any pinch points from boom
folding and movement.

RT200 interface module
The RT200 interface module contains
circuitry to interface boom-mounted sensors
with the user interface. The interface module
has serial, CAN, and power connections. It is
an environmentally sealed enclosure that can
be installed inside or outside the cab.
Mount the module in close proximity to the
center of the boom-mounted sensors (check
the length of cables 400-1-277 and 400-1-278
for suitable placement).
There are two small indicator lights on the lid.
The interface module has mounting brackets with drilled holes for mounting.
22

Installation and Setup
AgGPS FmX integrated display
Version 3.0 or later of the FmX integrated
display has a large color touchscreen and
integrated GPS and GLONASS receivers
for complete guidance, steering,
mapping, and application control.
The GreenSeeker plugin shows and stores
the data from the sensors, and
communicates with the applicator's rate
controller. The GreenSeeker plugin and
VRA unlock code are required to unlock
the GreenSeeker function on the display.
The FmX integrated display is not packaged with the GreenSeeker RT200 system. For
more information, see the AgGPS FmX Integrated Display Installation Instructions and
the AgGPS FmX Integrated Display User Guide.
GreenSeeker sensors
C
CAUTION – GreenSeeker sensors are designed to operate in harsh environments. The
sensor enclosure and connections are environmentally sealed. Although the sensor is
sealed, DO NOT wash the sensor directly with a high pressure washer. To clean the sensors,
use low pressure and gentle washing procedures.
The sensor takes reflectance readings. The units generate their own illumination for
use in any lighting condition, day or night. When the unit is on, a red band of light
shows directly below the rectangular sensor window.
The sensor operates by emitting light from the rectangular window onto a crop's
canopy. Reflected light from the canopy is focused on a detector behind the circular
window:
•
Both the rectangular and circular windows need to be free of any viewing
obstructions when mounted.
•
Mount the sensor so that there is at least 12'' (0.3 m) in front and 6'' (0.15 m) in
back of the lenses' peripheral view.
•
Keep at least 12'' (0.3 m) for the peripheral side view of the sensor free of objects.
The sensor is designed for an optimal height of 28'' to 48'' (0.7 m to 1.2 m) from the
rectangular LED window to the crop canopy. The extended range (with greater
deviation) is 26'' to 62'' (0.6 m to 1.6 m). The field of view (the width of the sensor
measurement) is ~24'' (0.6 m) within the sensor's optimal height range.
Sensor readings are nearly constant with the optimal height range, but will vary
somewhat over the extended range. Momentary movement out of the operating height
range does not significantly affect performance of the RT200 system, but take care to
keep sensors within the recommended height range most of the time.
GreenSeeker RT200 System Installation and Operation Guide

Installation and Setup
Mounting the sensors
26
•
Sensors are typically mounted using the standard
stainless steel bracket (provided). These
brackets are designed to fit most boom
structures.
•
The two outer sensors will have only one cable connected. The other port in the
outer sensors must be electrically terminated using a small plug device called a
CAN terminator. (The CAN terminator is usually pre-installed in two sensors.)
Mount these sensors in the outside (end) positions.
•
The bracket can be secured to most boom structures with standard size U-bolts.
One set of U-bolts is included with the system. Some booms may require
different U-bolts and/or custom fabricated brackets.
•
The sensor is bolted to the bracket with two 5/16" bolts (provided).
•
Sensors can be mounted in front of or behind a boom. The "direction" of the
sensor is not important, but the rectangular LED window must be parallel to the
applicator boom:
GreenSeeker RT200 System Installation and Operation Guide
2
Installation and Setup
•
For crops such as wheat and canola, the RT200 system works best when sensors
are evenly spaced across the swath of the boom. For example, if a boom is 60 feet
wide then the sensors would be spaced approximately 10 feet apart and the
outer two sensors would be spaced approximately 5 feet from the tips. Boom
folding procedures may prevent even spacing of sensors. This is acceptable as
long as the sensors are spread across the boom as evenly as possible. For row
crop applications, sensors must be positioned directly over a row. When used in
fields with a "guess row" or "wide and narrow row" you may have to mount the
sensor within your planter width.
•
Once the sensors are mounted, connect the sensor cables (400-1-265-240) as
shown in the system layout figure:
•
a.
These cables have a 12-pin connector on each end. Slide the connector into
one of the ports on the sensor with the keyed side towards the front of the
sensor.
b.
After firmly seating the connector, use a Phillips screwdriver to secure the
connectors retaining ring. It does not matter which port the 400-1-265-240
cables are connected to. The two outer sensors will have only one cable
connected. The other port in the outer sensors must be terminated.
c.
Insert the terminator (if not already installed) in the unused port of the
outer sensors and then secure the retaining ring.
As described in previous sections, use the 400-1-277 cables to connect the two
inner sensors to the interface module in the same way used for the
400-1-265-240 cables. Once all cables are connected, secure the cables to the
boom. Verify that cables will not be damaged by moving parts.
Product rate controller
Most applicators come with an installed product rate controller. The RT200 system
interfaces with most available controllers. If you have a rate controller that is not
currently supported by the RT Commander software, contact Trimble or your dealer to
inquire about obtaining support.
GreenSeeker RT200 System Installation and Operation Guide
27
2
Installation and Setup
GPS receiver
A GPS receiver is necessary for logging geo-referenced data and viewing on-the-go
mapping. An applicator may already use a GPS receiver for other operations such as
guidance. In many cases it can be shared. The RT200 accepts a serial connection
(RS-232) from a GPS receiver to the ruggedized PDA through a serial-to-USB converter.
Field preparations for nitrogen application
Field information
Before the GreenSeeker applicator can be used to apply nitrogen (N) across a field, you
must establish a nitrogen rich reference strip (NRS) before or shortly after planting.
This reference strip determines the amount of nitrogen being made available to the
plant by the environment mineralization and importantly, the present year's expected
maximum yield potential and response to additional nitrogen. The ideal NRS runs the
length of the field, but it should at least be 300 feet (91 m) long. Establish the NRS in a
representative portion of the field (that is, not in a high or low spot). The rate of N
necessary to establish a NRS depends on the crop and region, and should be equivalent
to the highest rate necessary to satisfy crop needs throughout the growing season. For
example, winter wheat grown in the Southern Great Plains should have a minimum of
100 lbs N/acre applied to establish the NRS. Lower pre-plant N rates should be applied
across the rest of the field. Application of 20 to 30 lbs of pre-plant N/acre would be
ideal for this situation.
The rest of the field is referred to as the Non-Reference (Non-Ref) portion. It may also
be referred to as the N-limited area or farmer practice region.
For best results, use the RT200 interface module to "read" the NRS and apply N at
growth stages dependent upon the crop algorithm used. For Trimble-supplied
algorithms the following is typically:
•
Wheat: Feekes growth stage 4-6
•
Corn: V8-V12.
For the sensors to accurately determine NDVI for topdressing (or sidedressing), plant
coverage should be at least 50%. The RT200 system with RT Commander can use the
sensor mounted booms to read the NRS, or the GreenSeeker handheld sensor can be
used to determine field conditions.
To collect sensor readings for the NRS, pass the boom-mounted sensor (or handheld
sensor) over the crop at 32'' to 48" (81 cm to 122 cm) above the canopy. Sense a large
area of the NRS and non-reference portion of the field to accurately determine their
respective NDVI values. Once you have measured the NDVI values, enter them into the
RT Commander software. You can do this automatically with the boom-mounted
sensors, or manually with the GreenSeeker handheld sensor. The RT Commander
software and the RT200 system allows for "straddling" the edge of the NRS and using
28

Installation and Setup
either the right side or left side of the boom for reading the respective areas, for
example, with three sensors over the NRS and three over the rest of the field. You can
also use the complete boom (with all sensors) to "read" NDVI in each area separately.
If response is obviously variable across the field, select an area where the difference
between the Reference and the Non-Reference areas are most apparent. This ensures
that the algorithm determines a rate that uses the highest yield potential prediction
and maximum response to N for that year.
To estimate yield potential, an environmental factor (Growing Degree Days) is used,
which takes into account weather and time since planting.
Note – Different GDD variations are used for different crops. To obtain the GDD value, you
need the planting date and sensing date. Regional values for GDD are available on the
Internet. For more information, see Where to Find GDD Information at
http://www.greenseeker.com/software/.
Setting up the field
1.
2.
Decrease the pre-plant Nitrogen (N) application rate of the field to a level at least
half of previous total N applied during non-GreenSeeker management practice:
–
For spring or winter wheat, if the application rate has historically been 100
lbs N/acre, decrease the rate to 50 lbs N/acre.
–
For corn, if application rates have historically been 200 lbs N/acre, decrease
the rate to 75 to 125 lbs N/acre.
Prior to or shortly after planting, establish the NRS (Nitrogen Rich Strip) in a
representative portion of the field (that is, not in a historically high or low spot).
Apply an applicator’s width swath of N. The rate of N applied should be high
enough to satisfy crop N needs in a good year:
–
For spring or winter wheat, the N rate should be at least 100 lbs N/acre.
–
For corn, the N rate should be at least 200lbs N/acre.
Use a marker to ensure that you can easily find the NRS later in the season.
The ideal NRS runs the length of the field, but it should at least be 300 ft (91 m)
long.
3.
At the appropriate crop growth stage, take readings of the NRS and an adjacent
part of the field to be fertilized. For the supplied algorithms the following is
typical:
–
Wheat: Feekes growth stage 4-6.
–
Corn: V8-V12.
4.
Find the area where the nitrogen rich strip is most apparent in comparison to
the rest of the field (this indicates greatest potential for the crop).
5.
Take sensor readings with the RT200 system or a handheld sensor to input to
the selected crop algorithm.

6.
Match nozzles and/or rate control system to maximize response time and
performance for each field's requirements. For more information, see Delivery
system and liquid control, page 47. Also refer to the application equipment and
rate control systems manuals.
Field preparations for user-defined rates (custom table)
Example: Cotton Defoliant
The RT200 system can be used to apply materials other than Nitrogen. The RT200
software permits a custom algorithm to be entered; this is a table of product values
compared to NDVI. A table has 16 points corresponding to an NDVI range of 0.25 - 0.88.
These values are entered directly on the RT Commander software screen (select Crop
Algorithm / Custom Formula).
Note – In RT Commander software version 1.3.x and later, there is also a high-resolution
100 point table option for NDVI values from 0.00 - 0.99. All points must have a value
entered.
Growers or crop consultants have historical crop knowledge that enables them to
determine different crop input requirements based upon biomass/size of the
crop/plant, for example, the variable rate application of defoliant in cotton. If this is the
case, the field is scouted or "field calibrated" to determine areas of the field that require
different rates of defoliant. The RT200 system or a GreenSeeker handheld sensor is
used to obtain the NDVI values in representative areas of the fiel, In the following
figure, the NDVI of the crop was measured under particular conditions for which the
grower knew the approximate required rate, using the GreenSeeker handheld sensor:
A table is then created with NDVI values corresponding to application rates. These
values are entered into the Custom Formula application table. See Appendix B, Custom
Algorithm.

The following table (and the resultant Calibration Graph) is an example for defoliant
variable rate application in cotton:
These values are only an example; the grower/consultant must develop these rates.
Also keep the rate range ability of the specific rate controller and nozzles used to
achieve these rates in mind when developing the rates.
To use the Custom Formula feature, you must enter some required values as shown
below. The default is zero; enter a value ( for example, 1) in the Non-Ref, Ref and RefPeak, and the GDD fields and then tap OK:

This chapter describes how to configure and use
the system.
The RT200 system can be used with either
version 3.0 of the FmX integrated display, or with
a PDA. This document describes the system
using a PDA; for information on the FmX
operation, see the Greenseeker chapter in the
AgGPS FmX Integrated Display User Guide.
The software interface of the RT200 system is the
RT Commander software or version 3.0 or later of
the FmX integrated display. The RT Commander
software was developed for use with a ruggedized
PDA powered by a Windows Mobile operating
system. Typically, RT200 systems are supplied
with a ruggedized PDA.
The software provides an interface where you
select setup features and enter operating
parameters. It can also display the current
system status and data logging capabilities. For
more information, familiarize yourself with the
PDA’s operating instructions.
This manual describes version1.3.x of the RT
Commander software. The operation is the same
as for version 1.2. However, additional
diagnostics functions and more options for
custom algorithms have been added.
GreenSeeker RT200 System Installation and Operation Guide

Configuration and Operation
Starting the RT Commander software
1.
Turn on the RT200 interface module, GPS, and rate controller (if applicable).
The RT200 green Power LED blinks three times, accompanied by three beeps
when it is first turned on. The Status LED will then blink corresponding to each
transmission of sensor data over the CAN bus. You will see a brief green flash,
followed by a red flash at the I/M message rate (typically at 0.5 sec), indicating
data from the Left and Right CAN ports, respectively.
2.
Turn on the PDA. When it starts, you may hear two separate "new hardware"
chimes:
–
The first chime indicates that the CF-to-Serial device is detected.
–
The second chime marks the initialization of the two additional COM
ports.
If no chimes are heard after the first five seconds, your PDA does not have the
chimes feature. If this is the case, wait at least 10 seconds before opening any
applications.
Do not launch the RT Commander software until you have heard both chimes
or until at least 10 seconds have passed.

Setup and configuration
The RT Commander software communicates with up to
three devices: the GPS receiver, the rate controller, and
the RT200 interface module.
You usually need to configure these devices only once as
the software retains the settings. You need to update the
setup parameters if new equipment is used with the
system.
Note – If you plan to only collect GreenSeeker sensor data
for mapping, you may skip the Controller section of the
setup.
Logging options
The Recording Interval is the rate at which data points are
written to the file. It defaults to 1000 ms (1 second) and
should always be less than or equal to the GPS rate.

Status tab
This shows the following details. Data here indicates
positive communication to these devices.
•
GPS detail status.
•
RT200 Sensor status. This includes the number of
sensors detected on system and error reporting.
The RT200 system monitors the sensors for correct
operation, and if a sensor reports erroneous data,
the data is not included in the rate control
calculation. Incorrect data can come from mud on
the sensor lenses, sensors viewing concrete, snow,
wet asphalt, or other non-soil or plant surfaces. The
Sensor Errors field reports the number of sensors
reporting NDVI out of expected values. For more
information, see Data output, page 44.
•
The RT200 interface module hardware and
software version report. This also confirms that the
interface module and user interface are
communicating. The NDVI shown is the combined
real-time value from all sensors on the left and
right booms respectively.
Note – The Version 1.2 Status screen does not show the NDVI table.
Errors tab
To make setup and troubleshooting easier, this tab shows
the ID and error codes from each sensor (version 1.3x of
the RT Commander software and later). Error codes are
short messages to help diagnose any problems related to
a sensor. The ID is the last two characters of the serial
number of the sensor.
NDVI values for crop analysis should range from 0.000 to
0.999. Therefore, the RT200 system uses negative NDVI
numbers to communicate error conditions to the RT
Commander software.
GreenSeeker RT200 System Installation and Operation Guide

Configuration and Operation
While the system does not enforce this, it is convenient to mount the sensors in
numerical order (by convention, with the lowest on the driver's left side) to aid in
diagnosis, or if doing high-resolution mapping with the RT220 system. If there is a
problem with a sensor or a connection, use this screen to isolate the location.
Error conditions
Error conditions include sensors disconnected from the CAN bus, or a sensor
transmitting invalid data. Invalid data could occur if the sensor malfunctions, or more
commonly, if it is seeing a target other than plants and soil. For example, when setting
up, the sensors may be pointed in the air, or against wet asphalt; either of these will
likely generate an error code from a sensor. The following errors are identified:

CAUTION – If the PDA has not been charged for several days, data will be lost. To avoid
this, do one of the following:
- Run the Backup Now utility installed on the PDA. This built-in backup is now done at the
factory to preserve the software installation. For information on using the backup utility,
see the Trimble Recon Getting Started Guide.
- Transfer the data from the PDA and save it to your computer.
- Copy the files to the CompactFlash card.
Application information
Delivery system and liquid control
As with any variable rate system, the minimum and maximum rates obtainable
depend on the delivery system. The RT200 system can request any rate, but the actual
rates delivered depend on the rate controller and its components. Most liquid rate
control systems control (“throttle”) the pressure of the system to affect flow and
application rate. There are also more advanced delivery systems that use two booms,
multiple nozzles, or special pulsing solenoids on each nozzle, to obtain larger rate
changes.
When using the RT200 system with a typical liquid delivery system, you must match
nozzle sizes to expected delivery rates. After the appropriate reference strip readings,
GDD, and selection of crop type are input into RT Commander software, the
application graph can be accessed to show the prescription rates at various sensor
NDVI readings. Review the Crop and Measurement screen features of the RT
Commander software to determine the expected delivery ranges in each specific field.
To do this, tap Show Table. Depending on the delivery system that is is used, there will
be actual minimum and maximum rates obtainable. These depend on components
such as the pump, control valve, nozzles, and boom plumbing sizes.
The RT Commander software has a feature that allows minimum and maximum rates
to be set, regardless of the crop algorithm prescription. Once you choose a nozzle set,
set the minimum at the lowest rate at which the nozzles will still give adequate
pattern/performance. Maximum rates may be limited by rates that lessen atomization
or drift.
GreenSeeker RT200 System Installation and Operation Guide
47
3
Configuration and Operation
Selecting a nozzle
It is usually best to match nozzles to the lower midrange of the typical rates shown on
the application graph. It is ultimately up to the grower or crop consultant to determine
the min/max rates and nozzles that are most appropriate.
Example
If most of your NDVI readings (in the area of the field not
in the NRS) are around 0.53, and the application graph
shows at 0.53 NDVI you should apply 15 GPA, select a
nozzle that can change rates above and below this NDVI
reading. You could select a nozzle that puts out 12.5 GPA
at its lowest pressure ( for example, 20 psi) and 21 GPA at
its highest pressure ( for example, 60 psi). Since the
penalty to under-fertilize (harm yield) is usually greater
than to over-fertilize (waste fertilizer), it may be best to
choose a strategy similar to the one shown here. Modify
the settings to fit your circumstances and to meet local
field and delivery system conditions.
Troubleshooting
•
If you do not hear the chimes after turning on the PDA (see Setup and
configuration, page 35) or do not get serial communication to GPS and/or the
RT200 system, perform a soft reset by holding the Power button down for
approximately eight seconds. Then turn off and turn on the PDA. If you still do
not hear the chimes, the PDA does not have a chimes feature—wait at least 10
seconds before opening any applications. Do not launch the RT Commander
software until you hear both chimes or until at least 10 seconds have passed.

Trimble recommends that you run a backup often to ensure you never lose any
data due to an unforeseen hard reset. For more information, refer to the Trimble
Recon Handheld Getting Started Guide.

If you do not see a black path being drawn on the map screen, verify that the
signal quality of GPS is set no higher than 1. Go to GPS Setup and then select the
Quality tab.
Note – Rate commands are not sent unless a valid GPS signal is received. If there is not an
adequate GPS signal, switch to GPS Setup / Simulation to set up the rate controller.
For more information, refer to the online troubleshooting document. Go to

The Custom Formula feature enables you to
select the application rates that will be applied at
different sensor readings. In version 1.3.x of the
RT Commander, software, you can add
interpolation to the 16 point table. A 100 point
table has also been added.
All positions in the 100 point table must have a
valid rate entered.
